WATER-ELEVATO R.

SPECIFICATION forming part of Letters Patent No. 565,800, dated August11, 1896. Application filed April 4, 1895. SerialNo. 544,461. (NomodeL)To all whom, it may concern.-

Be it known that I, DETALMO DI BRAZZA SAVORGNAN, of Rome, Italy, haveinvented a new and Improved .Water-Elevator, of which the following is afull, clear,and exact description. p

The object of my invention is to construct a water-elevator withoutcylinders, pistons,

or piston-rods, for deep wells, mines, and ex- IO cavations, in whichthe natural pressureof the atmosphere will be utilized in raising thewater. 7

My invention consists in a series of chambers provided with supply anddischarge pipes and valves and afloat-operated mechanism for opening andclosing the valves, all as will be hereinafter more fully described.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the views.

Figure 1 is a side sectional elevation of one of the water-elevatingchambers. Fig. 2 is a side elevation of a series of such chambersconnected with each other and with the vacuum-pipe. Fig. 3 is a sidesectional elevation of a modified form of vacuum-chamber. Fig. 4 is aside elevation of a series of such chambers connected together. Fig. 5is I a side sectional elevation of another modification on the line 5 5in Fig. (3. Fig. 6 is a partial horizontal sectiontaken on line 6 6 ofFig. 5. Fig. 7 is a vertical transverse section of another modification.Fig. 8 is a side elevation of a series of such vacuum-chambers, and Fig.9 is a modification of the form shown in Fig. 1.

The chamber A is divided into three compartments B C D, with a passage Eat the side of the chamber communicating directly and continuously withthe compartment B through the opening a, and communicating through theinclined valve-openin g b with the compartment D. The compartment Bcommunicates through the short U-shaped pipe 0 with the compartmentC,and the upwardlyturned end of the said pipe 0 is furnished with acheck-valve d, opening upward. In the wall of the compartment C isformed a slot 6, through which water may overflow into the compartmentD, and the compartment G communicates with the compartment D through thevalve-opening f in the bottom of the compartment. The valve-opening f isclosed by the valve g, which is attached to a curved arm 72., pivotedbetween ears 2', secured to the floor of the compartment 0. A stem jextends from the valve 9 downward through the val v e-opening f into thecompartment D. p l

In an upward extension 74; of the compartment D is placed a weightedvalve-carrying arm Z, which is bent at right angles and attached to a.valve m,.adapted to close the valve-openin g n in the side wall of theupward extension of the chamber D. The angled arm I is pivoted in abracket 0, extending inwardly from the wall of the compartment D, andthe said arm is furnished with a finger p, projecting into thecompartment D at right angles to the pivoted end of the arm.

In the upward extension q of the compartment D, communicating with thevalve-opening 19', is placed a vacuum-valve 1", which is attached to acurved arm 5, pivoted in the bracket 15, projecting from the wall of thecompartment D. The arm 5 is provided with a finger u, projecting atright angles toward the center of the compartment D. The arms Z and sare provided with weights which serve to hold the said arms and valvesattached to them in either an open or closed position.

In opposite sides of the compartment D are supported tubes c a? bybrackets 19, attached to the wall of the chamber A. The said tubes a aform guides for the float F. The float F is furnished with cars a, twoon either side, the apertures of which are prolonged to permit of thetipping of the float in the opera tion ofthe apparatus, as will behereinafter described. In the tubes a a are placed the rods d (1 The rodd extends downwardly toward the bottom of the chamber A and is benttwice at right angles, the end of the rod extending upward toward thefloat F. The

similar way the lower end of the rod (1 extends upwardly toward thefloat F, and the upper end is furnished with an angled arm 6 extendingdownwardly toward the floatF and provided with lugs f which embrace thefinger p of the valve-arm Z.

The chambers A are arranged one above the other in a series, thedistance between them being about equal to the distance through which apump can draw water. The top of each chamberis connected by a curvedpipe g with the vacuum-pipe G, which extends to a suitable vacuum-pump.The bottom of each chamber A is connected by a pipe H with the top ofthe next chamber above.

In the modification shown in Fig. 3 the chamber A is divided into twocompartments 0 D, and the compartment 0 communicates with thecompartment D through a slot 6 in the partition which separates theupper portion of the chamber A into two compartments. In the chamber Ais secured a tube a which extends through the compartments CD, but doesnot communicate with the compartment 0. On the tube a is placed acentrally-apertured float F, and in the tube a is placed a rod d havingits lower end bent at right angles and projecting through a slot in theside of the tube a below the float F. The rod 01 is provided with an arm8 which projects through a slot in the tube 603 above the float F. Theupper part of the rod 01 carries a valve m, which closes an opening atin the top of the casing, which is coincident with the bore of the tubea The upper end of the rod d is provided with two lugs f. In a standard0, projecting from the top of the casing, is pivoted a right-angledlever 19, the shorter arm of which extends between the lugs f of the rod(i and the longer arm. of the said lever carries a weight which swingsto one side or the other of the center of movement and holds the leverin either of the two positions in which it may be placed.

In the horizontal partition between the compartments O and D is formed avalve-opening f which is closed by a valve 9 attached to a curved arm kpivoted between ears 7?, projecting upwardly from the floor of thecompartment. The valve g is furnished with a stem j, which extendsdownwardly toward the float F. A pipe II communicates between the bottomof one chamber, A, and the top of the next chamber above in the series,and each pipe I-I near the bottom of the chamber A is furnished with acheck-valve I opening upwardly.

In the modification shown in Figs. 5 and 6 the construction is similarto that shown in Fig. 3. Therefore the same letters of reference willapply to like parts. In the said modification the lower portion of thechamber A is extended downwardly and the rod d and tube a are extendeddownwardly, the rod (1 being provided with a pair of lugs e e. The lowerend of the pipe H in this case is forked and the branches k kcommunicate with the lower part of the chamber A through valve-openingsZ Z which are on the same level. Angled levers m m pivoted in earsprojecting inwardly from the side of the easing, carry valves 91 nadapted to close the valve-openings Z Z The free ends of the levers m mextend between the lugs c e, projecting from the rod (1 and the leversare oppositely arranged with respect to each other.

In the branch of the pipe II is placed a ball 0 which is slightlyheavier than water, and the mouth of the branch 7 3 opening into thechamber A, is provided with a wire-cloth guard 19 The branch 70 of thepipe H at its juncture with the said pipe is provided with a wire-clothguard g for preventing the ball 0 from entering the said branch, and theupper end of the pipe H is provided with a similar guard g forpreventing the ball from going into the next chamber above.

The modification shown in Figs. 7 and 8 differs from the form shown inFig. 1 in the omission of the compartment B, the U -shaped pipe 0, thevalve 61, and pipe G, and in connecting the passage E with the pipe 11by the pipe G.

In the modification shown in Fig. 9 a waterreceiver 0 is formed on thetop of the float F and a valve-opening f is formed in the side of thewater-receiver and closed by a valve 9 carried by the valve-lever 72,pivoted to an arm projecting inward from the wall of the water-receiver.The upper arm of the valve-lever h is inclined away from the wall of thewater-receiver and provided with a weight which tends to keep the valve9 closed. An inclined plane 2' projects downward from the top of thechamber A in the path of the lever 72 so that when the float carries thesaid lever up into engagement with the inclined plane the valve 9* willbe opened. The vacuum-valve and air-valve in this case are operated bythe float in practically the same manner as described in connection withFig. 1, and friction-springs a", attached to the wall of the chamber Ato press the valve-rods and hold them in either of the two positions inwhich they may be placed.

In the form of my improved water-elevator shown in Figs. 1 and 2 theoperation is as follows: The pipe G being connected with a vacuum-pump,the air is exhausted from the entire series of chambers A, and the pipeH of the lower chamber of the series being inserted in the body of waterat the bottom of the shaft or well air-pressure causes the wa ter torise in the pipe H and enter the compartment B of the first chamber A ofthe series, and the valve m being closed and the valve 7' being open,and there beingfree communication through the slot 6 between thecompartments 0 and D, the water in the con1- partment B lifts the valvecl and flows into the compartment 0, and when the said compartment is'filled with water it overflows through the slot e'into thecompartment'D. As the lower part of the chamber Afills with water thefloat F rises, and coming into contact with the stem j of. the valveglifts the valve 9 and allows the water contained by the compartment toquickly flow into the-compartment A, thus causing the float F to risequickly. The arm 6, attached to the valveoperating rod d, being longerthan the arm 6 ofither'od d thesaid arm e is engaged by the float Fbefore the arm 6 and the vacuumvalve is closed against its seat, inwhich position it is held by the weight on the valvearm 8 and by thefloat. The apertures of the ears attached to the float being elongatedand the water] cohtin'uingtb flow into the lower part of the chamber Afrom the compartment 0, the free side. of the float continues to rise,

thus tipping it slightly and bringing it into engagement with the arm e?of the rod ri and the said rod by the engagement of the lugs f with thefinger p of the valve-arm Zopens the valve m, thus establishingcommunication between the interior of the compartment D and the externalair. At this point in the operation the valve 01 closes and watercontinues to flow into the compartment B, the communication between thiscompartment and the vacuum pump not having been broken. The pipe H isconnected with the bottom of the chamber A and communicates with the topof the compartment 13 of the next chamber above, and the air having beenexhausted from the next chamber above the water contained in the lowerpart of the lower chamber is forced by atmospheric pressure upwardlythrough the pipe H and delivered to the compartment B of the secondchamber in the manner already described in connection with the first,when the same series of operations occurs in the second chamber, and assoon as that chamber is filled the vacuumvalve 1" of that chamber isclosed and the water contained by the second chamber is elevated to thethird. In the first or lower chamber as the water is discharged thefloat F descends, and when it reaches its lowest point it first strikesthe angled end of the rod d forcing the said rod downwardly, and byvirtue of its engagement with the lever of the valve m closes the saidvalve and thus shuts off communication with the external air, and theopposite side of the float descends, openingthe vacuum-valve, whenpressure is equalized in the various chambers, and water again overflowsfrom the compartment B into the compartment 0 and the operation alreadydescribed repeats itself.

The operation of the modified form shown in Figs. 3 and 4: is asfollows: The upper end of the pipe H is connected with a pump and theair is exhausted from all of the chambers A, the valve m being closed.The lower end of the pipe H being immersed in water, water is forced byatmospheric pressure through the pipe H and delivered to the compartment0. When this compartment is filled,- the water "overflows" through theslot 6 into the compartment D and the float F" rises, being guided bythetube a Asthefloat nears the upper limit of its -n1ovement itstrikesthe stem j of the valve ghopeningthe said valve and allowingthewater to'flow from thecomp'artment O to the compartment D, thus suddenlyadding to the volume of the water in the compartment Dycausing the floatF to rise farther and open the valvemfby its engagement with the lug eThe air entering "through the tube a forces the water upwardly "throughthe pipe H into the'next chamber above, and when the next chamber aboveis filled the float opens the. air-valve of that chamber andwateriscarried from that chamber. to the thi'rd,and soon throughout-theseries. As the water is-discharged from the lower' chamber A the float'Fdescends,and

engaging the angled'lower end of the rod d "closes the valve'm, when theair is a-gai nex- 'hausted from the *chamberA and *what has I alreadybeen'described' is repeated.

It will be noticed tha tboth air and water ascend through the pipe 11'.

It will also" be noticed that the weighted lever 13 'holdsthe valve m ineitherof the two positions in which it is placed until the valve-rod isagain. moved by the float.

In the modification shown in Figs. 5 and 6 the operation is like thatdescribed in connection with Fig. 3, except as regards the forked pipeH. In this case the branch k of the pipe H is closed by the valve itwhen the float F is raised, and the valve 11 is then opened, so thatmost of the water passes through the branch 71: but when the floatdescends far enough to close the valve 01 and open the valve n the waterremaining in the pipe H is preserved in a solid column by the ball 0which nearly fills the pipe and thus permits of carrying the entirecolumn of water upwardly and discharging it into the next chamber above,and after its upward excur sion the ball 0" returns it to the lowestposition by its own gravity. It will thus be seen that the branches k ofthe pipe H are alternately opened and closed as the float rises andfalls.

In the modification shown in Fig. 7 the operation is substantially likethat of the form shown in Fig. 3.

In the form shown in Fig. 9 the extra supply of water for causing thefloat to operate quickly during the latter part of its upward travel iscarried by the float itself,and when it is discharged into the chamberit not only augments the supply of water which forces the floatupwardly, but the discharge of the water lightens the float andincreases itsbuoyant power.

It will be seen that in the modifications shown in Figs. 3 to 7,inclusive, the water which enters the chambers D and D will have to passthrough the whole series and be discharged from the system before avacuum can again be established in the lower member of the series and aflow be reestablished.

By inclosing the float-rods in tubes and employing the tubes as guidesfor the float the float is kept out of frictional contact with the rods,and positive action is insured.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a water-elevator, a chamber having afloat-compartment, and a water-receiving compartment having an overflowdischarging into the float-compartment, a valve-operatiu g float placedin the float-compartment, a floatoperated valve for controllingcommunication between the water-receiving compartment and thefloat-compartment, and air and vacuum valves for controlling theadmission and escape of air, substantially as specified.

2. In a Water-elevator, a chamber having a floatcompartment and a waterreceiving compartment having an overflow discharging into thefloat-compartm cut, a valve-operating float placed in thefloat-compartment, a floatoperated valve for controlling communicationbetween the Water-receiving compartment and the float-compartment, awater-suction pipe, a vacuum-pipe, and a water-reservoir in constantcommunication with the vacuumpipe, substantially as specified.
